Problems solved by technology

[0002] With the enhancement of social environmental protection awareness and some obvious advantages of electric vehicles, the number of electric vehicles is rapidly increasing, but the charging problem of electric vehicles has also received great attention. The charging of electric vehicles is relatively troublesome, and many charging problems have not been resolved. It can be completely solved, especially the garage parking spaces of many families are not equipped with charging piles, the charging current is large, the load is heavy, and the number of charging stations in some places is very small, and electric vehicles have to be plugged in and charged every day. It is relatively troublesome, which has always troubled consumers and the convenience of using cars, which has restricted the promotion and popularization of electric vehicles;

[0003] In addition, the previous solar energy systems were deficient and lacked practicability, and could not be promoted and recognized in actual life consumption, as follows:

[0004] 1. In the design of other parts of the solar energy system, the power generation characteristics of the solar panels are not targeted, the voltage conversion and maximum power calculation control are lacking, and the solar panels are not effectively controlled to be in the state of maximum power generation, resulting in a serious reduction in conversion efficiency and power generation. Significantly reduced, the power generation effect is weak, this problem is very serious, and it is a key shortcoming that causes the charging capacity to fail to meet the requirements of practical applications;

[0005] 2. In the case that the electricity generated by the solar panels or the converted voltage cannot directly charge the power battery, in the past solar charging schemes, there is a lack of connection, communication, docking, and control functions, and it cannot be docked and charged for vehicles in reality. , failed to solve the practical problem of solar charging, and failed to apply to actual charging;

[0006] 3. In addition, the charging requirements and safety level of electric vehicles are very high. In the battery application of electric vehicles with high safety, the previous solar charging scheme lacked independent voltage detection and monitoring heating, and it was easy to overcharge and damage the battery. or cause battery safety issues;
